How bands work: every band is a fixed fraction of Band D, set in law (Band A is 6/9 of Band D and Band I 21/9), rounded here to the penny. A home's band comes from its value on 1 April 2003: Band A up to £44,000, Band I over £424,000. Payments are the yearly charge divided by 10 or 12. Other bands may differ by a penny from your council's table because of how councils round.
